Introduction

1.1 Introduction to the H-2191 and H-2192

Both the H-2191 and H-2192 are modem based communication devices. The main difference is
the H-2191 is based on a standard land line connection while the H-2192 uses a cell phone based
modem for communications.

NOTE: Items discussed in this manual that apply to both the H-2191 and to the H-2192 will be
listed as H-219X. Subjects that pertain only to one unit or the other will use the appropriate
model number.

The H-219X data/voice modems operate in a fashion similar to many other modems, but they
also have been designed with special features that make them ideal for remote applications in the
data logging industry. While in a sleep mode, the H-219X draws very little power making them
ideal for battery operation. The advanced setup options are easily programmed through the serial
port or remotely via a data connection. The H-219X operate in several different modes.

Voice Call In Over Land Line or Cell Phone:
When called, the H-2191 will answer in a voice mode and later switch to a data mode if
necessary. The H-2192 acts the same as the H-2191 except it will not enter a data mode. The
voice mode allows the user to retrieve data by simply calling the H-219X from any touch tone
phone. Data for the voice mode normally comes form a WATE RLOG series data logger.

®

Voice Call Out (ALARM) Over Land Line or Cell Phone:
The H-219X can also call out in a voice mode when an alarm condition exists.

Voice Over RF Radio Link:
This is the same as the land line or cell phone operation except the alarm call out option is not
supported. To call a site, instead of a phone number, a 2 to 4 digit code pressed on a keypad of
the calling radio is used.

Data Over Land Line Connection:
In the data mode, the H-2191 may be used to program or retrieve data from any WATERLOG
series data logger through the serial port. The connection is made using a terminal emulation
program such as Hyper Term running on a PC with a standard modem.

Data Over Cell Phone:
In the data mode, the H-2192 may be used to program or retrieve data from any WATERLOG
To access the data logger using the cell phone modem a TCP/IP connection must be used. This
can also be done using the Hyper Term program.

®

H-219X Introduction 1-1

Text Message Call In Using The Cell Phone:
The H-2192 can also send data in a text message. To receive a text message with the data simply
send a text message to the H-2192. The H-2192 will reply to the calling number with the current
data.

Text Message Call Out (Alarm) Using The Cell Phone:
The H-2192 can also send data in a text message based on some alarm condition. When an alarm
condition occurs, the H-2192 will send a text message to selected recipients unsolicited.

1.5 H-2192 SIM Card Installation

Before the H-2192 GSM cell phone modem can be used a SIM card must be obtained and
activated by a local provider, then installed in the modem.

Use the following steps to install the SIM card.

1 - Remove the two screws on the end of the case with the LED’s and ground lug.

2 - Disconnect the ground lug from the end plate by pulling gently on the connector on the
ground wire. Be careful not to bend the end plate. Also be careful not to pull the end plate away
from the case to the point the antenna wire disconnects or is stressed.

3 - Holding the other end plate in one hand, gently pull the top half of the case away from the end
plate exposing the PC board inside. With the top of the case slid back about half way the modem
module will be exposed.

4 - At one end of the modem module will be a socket for the SIM card. Properly orient the SIM
card to the socket and insert it into the socket.

5 - Push the top of the case back into its normal position.

6 - Reconnect the ground lug wire to the end plate.

7 - align the end plate and replace the two screws.

Note: If the antenna cable did become disconnected from the modem module, then simply
reconnect it. Be careful as this is a small connector and does not take a lot of pressure to
reconnect it.

1.6 FCC Approval

Type of Service: The H-2191 is designed to be used on a standard device telephone line. It

connects to the telephone line by means of a standard jack called the USOC RJ-11C. Connection
to telephone company provided coin service (central office implemented systems) is prohibited.

Connection to party line service is subject to state tariffs.

Telephone Company Procedures: The goal of the telephone company is to provide the best
service possible. In order to do this, it may occasionally be necessary for them to make changes
in their equipment, operations, or procedures. If these changes affect your service or the
operation of your equipment, the telephone company will give you a written notice in order to
allow you to make any changes necessary to maintain uninterrupted service.

In certain circumstances, it may be necessary for the telephone company to request information

1-4 Introduction H-219X

from you concerning the equipment which you have connected to your telephone line. Upon
request of the telephone company, provide the FCC registration number and the ringer
equivalence number (REN); both of these items are listed on the equipment label. The sum of all
the REN’s on your telephone line should be less than five in order to assure proper service from
the telephone company. In some cases, a sum of five may not be useable on a given line.

If Problems Arise: If any of your telephone equipment is not operating properly, and you expect
it may be affecting the telephone line, immediately remove it from the telephone line to prevent
harm to the telephone network. If the telephone company notes a problem, they may temporarily
discontinue service. When practical, they will notify you in advance of this disconnection. If
advanced notice is not feasible, you will be notified as soon as possible. When you are notified,
you will be given the opportunity to correct the problem and be informed of your right to file a
complaint with the FCC. Contact your telephone company if you have any questions about your
telephone line. In the event any repairs are required on the H-2191, they should be performed
only by Design Analysis Associates. In this event call Design Analysis Associates for assistance.

2.2.1 Phone Connection

The phone connection is a standard RJ11 connector allowing a simple connection to a phone
system.

2.2.2 Cell Phone Antenna Connection

The H-2192 uses a built in cell phone that uses this connection for its antenna.

2.2.3 RF Radio Connection

This connection was designed to plug directly into a Data Radio DL-3400 RF radio using a
straight through cable. This connection handles the audio in and out, the push to talk (PPT)
function, and other control signals. The H-219X also controls the power to the radio so it can be
turned off to save power.

2.2.4 Earth Ground Connection

There is a connection for an earth ground. It is very important that an earth ground be provided
and connected to this grounding post on the H-219X. Other equipment in the system should also
be connected to an earth ground.

H-219X Installation 2-3

2.4 LED Descriptions

DTR LED:

The DTR LED indicates the data logger connected to RS-232 port is active. This LED will be on
any time the data logger is sending data to the modem, any time the modem requests data from
the data logger, and when a data connection is active.

Modem Pwr:

On the H-2191, the modem is normally turned off and the unit is in a low power mode.
Incoming calls will be detected and wake up the modem. Once the modem is awake the call can
be answered.

On the H-2192 the modem power must be on to receive a call. For the H-2192 the power can be
programmed to turn on and off and set times or based on a battery voltage, or on always.

DCD LED

This is the Data Carrier Detect signal form the modem used in the H-2191. When a data
connection is valid this LED turns on.

Link LED:

When using the H-2192 this LED indicates the status of the cell phone connection. This LED is
off if the internal modem module is powered off. This LED is on solid if the modem power is on
and the cell modem is not registered on the network. This normally only happens for a few
seconds when the modem module is first powered up. This LED will blink at a rate of once
every 2 to 3 seconds when it is registered on the network and ready for operation. If a call is
active then this LED blinks at a faster rate of about 1 a second.

DL3400 Radio Pwr LED:

The VHF or UHF radio must be powered for operation. This LED indicated the status of the
power supplied to the radio.

NOTE: The Ethernet connector has a couple of LED’s on it also, but it is not activated at this
time.

vary according to your intended application and site conditions.

! Choose the best place to mount the equipment. Wiring should be kept as short as

possible. Equipment with displays and keyboards should be easily accessible. Equipment
with exposed wiring terminals should be mounted with the terminals toward the bottom
of the case. Antenna cables should be kept short. Also consider any future expansion,
function of the equipment, vandalism, etc.

! Physically mount all the equipment in the desired locations.

! Connect a power source to the H-219X. This power source should be a 12 Volt power

source, but not to exceed 16 Volts. Use 18 gauge wires or heavier for a standard modem
application, if the RF radio is used then use 16 gauge or larger wires for the power .

! Connect the phone line to the phone line connection of the H-2191 using a standard RJ11

connector. For the H-2192, cell phone sites, install and connect the antenna.

! For sites using the RF radio, install the radio and make appropriate connections as

H-219X Installation 2-5

needed. This includes the data / power cable, and antennas.

! On sites using the H-2192 cell phone and an RF radio, install the antennas and cables to

prevent the two from interfering with each other.

! Connect the RS-232 cable to the XL series data logger or other equipment. When

connected to the XL series data logger a straight through cable should be used, a NULL
modem adaptor is not required.

! Evaluate the earth grounding of all the equipment at the site and make sure the modem is

included in this grounding scheme. An earth ground connector has been provided for this
purpose.

2.6 Testing the Installation

The H-219X is designed to be a plug and play device. Once connected, it should function without
any additional setup in the data mode and only a few settings for the voice mode. Normally the
voice mode settings of the H-219X will be setup in the office, but they may also be done in the
field. This includes adding the voice messages and any settings for the stand alone mode. See the
next chapter for details on the voice mode setups.

Before leaving a site, make sure the equipment is functioning properly. The best way to confirm
that the H-219X is connected properly and operating properly is to call it. The voice mode is the
easiest to test. If a cell phone is available, call the H-219X and the voice sign on message should
be heard. Run through the different options to verify that they are all working correctly. A
common problem is that the messages do not match the data, for example the first message may
refer to stage when the data reported is temperature. Either change the messages to correspond to
the data or rearrange the order of the data being sent to the H-219X.

To test the data mode, it is again best to call the site and verify the connection and operation.
When used with an XL series data logger, pressing the enter key a few times should produce the
arrow prompt used by the command mode of the data logger or a menu will be displayed. If the
command prompt is displayed then standard commands for the XL series logger may be used. If
the menu is displayed then the menu may be accessed as usual.

It may also be helpful to hook a current meter to the H-2191 and monitor the power consumption
of the H-2191 in its sleep mode, voice mode, and data mode. See the specifications for the actual
levels.

2-6 Installation H-219X

Chapter 3

Operation

3.1 Overview

The H-219X is easy to set up and operate, and can be used as a regular data modem as well as a
voice modem. The modem uses the standard AT and S register commands, however in most
cases they are handled automatically so the user does not need to know anything about them.
Options related to the voice mode of the H-219X are programmed using a built in menu or from
an extended set of commands.

3.2 Data Mode Operation Over Standard Phone System

The main purpose of the H-2191 in the data mode is to allow data communications between a PC
and a remote WATERLOG series data logger. This allows for remote data transfers, and for
changes to the data logger setups remotely. If the H-219-1 is operated with a WATERLOG series
data logger, all that needs to be done is to connect the power, the RS-232 cable, and the phone
line to the H-2191.

Although this may seem too simple, the system is designed to be a plug and play system,
meaning that only a few steps are necessary for operation. If you are going to use the modem
with something other than a WATERLOG series data logger, standard AT commands and S
registers may be changed for special modes if needed. In most cases no changes are needed.

When used in the data mode only, no setup changes are required on the data logger. This is the
simplest mode of operation.

Note: The H-2191 is configured to always answer in the voice mode. When the H-2191 is

called it first looks for a keyed response from a touch-tone phone in order to continue
with the menu for voice capability. If it does not receive a keyed response within five
seconds, the H-2191 will automatically switch to the data mode and expect to
communicate with another modem in a data mode.

3.3 Voice Call In Over Standard Phone System

®

®

Before proceeding, an explanation of how and what data will be sent from the data logger to the
H-2191 modem may be helpful.

3.3.1 Voice Call In Overview

When a incoming call is made to get data from a site in a voice mode, the data spoken is data that
resides in the modem, not the logger. On the XL series of loggers, there is a special menu option
to define what data will be sent to the modem and the order in which it will be sent. This data is

H-219X Operation 3-1

normally sent to the modem each time the logger scans the different sensors. For example if the
logger is set to scan the sensors every 15 minutes, then data is normally sent to the modem every
15 minutes. For more instructions on this feature, please see the corresponding section in the XL
Series data logger owner’s manual.

The data coming from the data logger will be stored in memory locations referred to as data value
boxes within the H-219X. There are ten data value boxes labeled BOX01 to BOX10. As data is
sent from the data logger to the modem it is placed in data box01 and continues until no more
data is sent or all the data boxes are full. A time stamp is also sent to the modem so the time the
data value was measured is known. The following table gives a simple visual representation of
how data is stored in the modem.

Time Stamp Box 01 Box 02 Box 03 - - - Box 10

Each data box has a user programable message that will be spoken to identify the data when a
voice call is made. A typical message would look like the following:

“The battery voltage is $v01 volts”

Notice the ‘$’ character in the message. The ‘$’ is used by the system to perform some task at
that point. The character just after the ‘$’ indicates the action to take. In this case the next
character is a ‘v’ which stands for ‘data value’. So in the above message the $v01 means insert
the value from data box 01 into the message when it is spoken.

For example, if the value in box01 is 34.25 and the user programmed the message for box01 to
“The stage is $v01 feet” then the unit would speak “The stage is 34.25 feet", and then move on to
the next data value if it is valid.

Now besides there being 10 different data boxes like a columns a table, there are also multiple
rows to hold older data.

Currently, this is a 10 by 13 table used to hold the data values. This is basically 10 values wide
for the different types of data and 12 values deep for historical data. One extra row of data for
non scheduled updates.

Time Stamp Box 01 Box 02 Box 03 - - - Box 10

Last / Non Scheduled Update

Last Update

3-2 Operation H-219X

Historical Data 01

Historical Data 01

| | | | | |

Historical Data 12

The normal sequence for a data logger to load data into the modem at a normal scheduled update
time is as follows:

AV Send the AV command just to get its attention
AVTIME=HH:MM:SS Send the time to the modem, time is stored in top box in the table.
AVBOX01=12.34 Send data for data box 01, data stored in top box of the table.
AVBOX02=56.78 Send data for data box 02, data stored in top box of the table.
AVSHIFTVALUES Shift values so data in row 12 is lost, row 11 moved to row 12, row

10 moved to row 11, continued on until row 0 is stored in row 1.

If the user requests data on demand, then the same sequence is followed except the shift
command is not issued. The new data is in row 0 and all the historical data in the other rows
remains the same. Again the data logger automatically issues these command to load the data
into the modem.

3.3.2 Voice Call In Options

On the XL Series data logger use the ‘Voice Modem’ options menu to select what data will be
sent to the modem, how often and in what order. Refer to the XL Series manual for full details
on setting up the voice modem options.

On the H-2191 modem, the main setups required are to enter the voice messages that will be
spoken when the modem answers the call. This will be a site identification message and any
messages needed to identify the data values. To use the menu to make these changes, connect a
PC to the RS-232 port and using Hyper Term enter the following commands to get he menu.

AVMENU

After entering the above command the following menu will be displayed.

Use the options 0 to 9 to change the messages that will be used to identify the data values.

Use the ‘A’ option to enter the Alarm Message Menu to customize messages sent during an
alarm event. Alarm messages are used only for outgoing calls and text messages and do not need
any changes if only incoming calls will be used.

All messages can be up to 128 characters.

3.3.2.1 Embedded Control Codes and Special Characters

The H-2191 has a text to speech converter so the messages typed will be spoken when called.
The unique exception is the ability to embed control codes in the text. This allows the messages
to actually speak the data values or perform other actions. The embedded control codes all start
with the ‘$’ character. As the unit is speaking the message and it sees the ‘$’ it knows a special
case exists and looks at the next character to see what action to perform. This is not case
sensitive. The following table shows all the special cases.

Code Action

$Vxx The ‘V’ character stands for value. This control code is used to

insert a value into the data message. The value comes from the
data box indicated by the xx. The xx has a range of 01 to 10.
The leading zero is needed.

$Q This code is used to ‘Q’uit speaking the current message and

move on to the next message if one is needed.

$I This code inserts the current IP address assigned to the modem.

$P This code inserts the current TCP port set in the modem

Some characters cause the ‘text to voice’ converter to speak a work or perform some other
function. These are listed in the following table.

Character Spoken Text

= Speaks the word ‘equals’

, Causes a pause of 0.5 seconds

H-219X Operation 3-5

. Speaks the work ‘point if in a

number such as 12.34.
Causes a pause of about 1 second
if at the end of a word.

< Speaks ‘Less Than’

> Speaks ‘Greater Than’

# Speaks ‘Number’

% Speaks ‘Percent’

& Speaks ‘and’

Other unique characters may speak a word or phrase but are normally unusable for this
application and can be spoken by spelling out the word if needed.

3.3.3 Phone Call In Menu

When calling the H-2191 it will respond with the message: “Press Zero For The Menu”.
Pressing the '0' key on the phone will cause the H-2191 to ‘speak’ its ‘Call In’ menu. This menu
with its options is listed below:

Press: 1 for a new measurement.

2 for the last measurement.
7 to move forward in time
8 to move to current time
9 to move back in time
0 to repeat the menu.

Pressing '1': This instructs the H-2191 to request a new measurement from the XL Series

data logger. This may take several seconds and is based on the type of sensors
connected to the logger.

Pressing '2': This causes the H-2191 to ‘voice’ or speak the last measured data from the

logger.

Pressing '7': When moving through the historical data, this key causes the H-2191 to move

forward in time. This is used in conjunction with the ‘9' key which moves
back in time, and the ‘8' key which moves to the current time. These options
allow historical data to be reviewed to look for trends in the data. The modem
will hold 12 historical data values for each data box. When these options are

NOTE: The following are valid options that are not part of the spoken menu. Press the ‘*’

key to access these options

Pressing '*1': This is a hidden option to instruct the modem to answer in a data only mode on

the next dial in attempt.

Pressing '*2': This is a hidden option to change the modem to modem baud rate on the H-2191.

Pressing '*4': This is a hidden option in the call in menu and is used to enable the alarms.

Pressing '*5': This is a hidden option in the call in menu and is used to disable the alarms.

Pressing '*6': This is a hidden option to acknowledge any pending or suspended alarms.

Pressing '*8': This is a hidden option in the call in menu and is used to enter a menu used to

adjust the voice quality options while the user is on the phone listening to the
adjustments as they are made.

Pressing '#': This is a hidden option that causes the call to terminate immediately. The ‘Good

Bye’ message will be spoken and then the phone call is terminated. The normal
inactivity timer of about 7 seconds is ignored.

The modem will ‘voice’ a good-bye message and hang-up if there is no key press for about 7
seconds.

3.4 Voice Call In Over Cell Phone System

Calling into a H-2192 functions the same as calling into the H-2191. The only difference is the
modem module power must be enabled, keeping the Cell phone module active.

H-219X Operation 3-7

The Cell phone modem module can be powered up all the time or off all the time. It can be
programmed to turn on and off at set times, or based on the level of the battery voltage. The
following menu is used to select how the power for the cell module is handled.

H-2192 Cell Phone Menu

P - Power On/Off: Off (Manual Off)

Last Time Update: 00:00:00

V - Cell Carrier Password:

This is a GSM only option and sets the password if required for the GSM provider.

Current IP Address:

This field shows the current IP address assigned to the modem. If the address listed is 0.0.0.0
then the cell modem isn’t powered or the cell provider hasn’t assigned it an IP address.

I - TCP Listen Port Number:

This option sets specifies the TCP port number which the modem is going to listen for incoming
connections. Note: If you specify port 0 it will disable incoming data connections.

Last Time Update:

This is a status message that shows the last time data was loaded to the unit. This time stamp is
used by the modem to see if it should turn on or off the modem based on the turn on time and the
turn off time settings and the power mode setting.

Keep in mind there is no time clock in the H-219X so all calculations and decisions using a time
value are based on the time received from the data logger. Remember that if the data logger is
using international standard time and not local time, then that is what is sent to the modem.

H-219X Operation 3-9

3.5 Voice Call Out (ALARM) Over Standard Phone System

The H-219X provides the option to alert a user of an alarm condition at the site installation.
There are two methods of alarming with the H-219X.

The first method of alarming the H-219X is provided with a External Alarm Input located next to
the +12V power connection on the modem. This input is pulled high internally to 5 Volts by a
47K resistor and is triggered by pulling the line to 0 Volts (GND).

The second method of alarming is provided by XL series data logger attached to the RS-232 port
of the H-219X. Please refer to the data loggers documentation on triggering H-219X alarms.

Alarms persist until acknowledged or the system loses power. If an alarm fails to get
acknowledged it is suspended until the next report issued by an attached data logger.

3.5.1 Voice Call Out Menu

When an alarm is activated the H-2191 will call out to the programmed phone numbers and if
answered will respond with the message: “Press Zero For The Menu.” Pressing the ‘0' key on the
phone will cause the H-2191 to ‘speak’ the alarm message and then the ‘Call out’ menu. The
options for the call out menu are listed below: If no key is pressed for about 7 seconds the
modem will speak a ‘Good bye’ message.

Press: 1 for a new measurement.

2 for the last measurement.
3 to repeat alarm messages.
4 to enable alarms.
5 to disable alarms.
6 to acknowledge alarms.
7 to move forward in time
8 to move to current time
9 to move back in time
0 to repeat the menu.

Pressing '1': Instructs the H-2191 to request a new measurement from the data logger. This will

take at least 15 seconds and may be longer based on the setup options of the data
logger.

Pressing '2': This causes the H-2191 to ‘voice’ the last measured data received from the data

logger.

Pressing '3': This causes the H-2191 to repeat any alarm messages for alarms that have gone

active.

3-10 Operation H-219X

Pressing '4': This causes the H-2191 globally enable the alarms.

Pressing '5': This causes the H-2191 globally disable the alarms.

Pressing '6': This causes the H-2191 acknowledge the alarm call out action.

Pressing '7': When moving through the historical data, this key causes the H-2191 to move

forward in time. This is used in conjunction with the ‘9' key which moves back in
time, and the ‘8' key which moves to the current time. These options allow
historical data to be reviewed to look for trends in the data. The modem will hold
12 historical data values for each data box. When these options are used the
modem will ‘voice’ or say “Scan XX” where XX is a number 0 to 12 indicating
scan number 0, the newest scan, to scan number 12, the oldest scan, after which it
will voice the data in each data box for that scan.

Pressing '8': This causes the H-2191 to move to the last measurement and ‘voice’ or speak the

data measured by the logger at that time.

Pressing '9': This causes the H-2191 to move back in time so historical data can be reviewed to

look for trends in the data. This is used in conjunction with the ‘7' key. See the
description above for the ‘7' key for more information.

Pressing '0': This causes the H-2191 to repeat the menu.

Pressing '#': This is a hidden option that causes the call to terminate immediately. The ‘Good

Bye’ message will be spoken and then the phone call is terminated. The normal
inactivity timer of about 7 seconds is ignored.

3.6 Voice Call Out (ALARM) Over Cell Phone System

Out going calls over the Cell Module based on an alarm condition will act much the same as for
the standard phone system.

3.7 Data Call In Using Cell Modem Module

Note: a data plan setup for mobile terminated connections is required for this feature to be
available. The modem will listen for incoming telnet sessions on the TCP port specified by the
user (the default is port: 2192). Simply open a connection with a program like HyperTerminal
using the port and IP address assigned to the modem (refer to the cell providers documentation
on obtaining the IP address which they assigned to the modem).

H-219X Operation 3-11

3.8 Text Message Call In

The H-2192 can text the last measurement over the cell network. To us this feature simply send
a text containing any content to the phone number of the H-2192 and it will respond with the last
measurement reported to the modem.

3.9 Text Message Call Out

The H-2192 can text an alarm rather than make an outgoing voice call. This feature can ben
enabled by prefixing the provided phone number with the character ‘T’
For example: if I wanted to text to the phone number 555-555-1234 I would enter the phone
number as T555-555-1234 under the H-2192 alarm menu.

If both voice and text alarms are enabled the alarm will continue to be active until acknowledged
from a voice alarm. If only text alarms are used alarms continue to be active until the alarm has
been successfully sent to all configured recipients.

3.10 Voice Call In Over UHF / VHF Radio

The H-2191 can connect directly to a Data Radio DL 3400 radio. Using this radio, data
messages can be ‘spoken’ as requested from remote sites using similar radios with the ability to
produce a DTMF tones. Basically a radio with a phone like keypad will be able to produce the
DTMF tones.

Calling into a H-2191 that uses a UHF /VHF radio will act much the same as calling in from a
standard phone system. The main difference is only the last measured data will be spoken and
the user must use a keypad on their radio to select the site they want data from.

The Radio can be powered up all the time or off all the time. It can be programmed to turn on
and off at set times, or based on the level of the battery voltage. The following menu is used to
select how the power for the radio is handled.

H-2191 RF Radio Menu

P - Power On/Off: Off (Manual Off)
I - Radio ID Code: 0

Last Time Update: 00:00:00
N - Radio Turn On Time: 06:00:00
F - Radio Turn Off Time: 18:00:00
V - Radio Turn Off Voltage: 12.25

Enter Option -> _

3-12 Operation H-219X

P - Power On/Off:

This option selects if the cell module is powered on, off or auto. In the auto mode the modem
will power up and down automatically based on the turn on time and turn off time settings.

I - Radio ID Code:

This option is used to select a 1 to 4 digit ID code to use to call the site. Each site must have a
unique ID. The default ID code is ‘0'. The H-2191 considers the default ID of ‘0' as invalid
forcing the user to set this to a unique ID.

N - Radio Turn On Time:

This option sets the time the modem will turn on the attached radio if the power mode is set to
‘Auto’.

F - Radio Turn Off Time:

This option sets the time the modem will turn off the attached radio if the power mode is set to
‘Auto’.

V - Radio Turn Off Voltage:

This option sets the minimum battery voltage level before the modem will turn off the radio
automatically. This will turn the radio on and off no matter what the power mode is set to. This
may be set to 10 to 14 volts. The default is 12..25 volts. This will help prevent the radio from
draining the battery.

Last Time Update:

This is a status message that shows the last time data was loaded to the unit. This time stamp is
used by the modem to see if it should turn on or off the radio based on the turn on time and the
turn off time settings and the power mode setting.

To call a site using the RF radio the user presses the PTT (Push To Talk) button on there radio
and then keys in the ID code using the keypad on their radio. Once the ID code is entered,
depress the PTT button. At that point if the receiving site recognizes the ID it will speak the data
from the last measurement.

Modem Command Reference

4.1 Introduction

The H-219X uses a modem module that incorporates the standard Hayes AT command set. However
the modem module is just one subsection of the H-219X. In most cases the user will never have to
change the configuration of this module. The H-219X has much more capability than just a standard
data modem. The H-219X also supports voice options over the phone system, Cell phone options,
alarm call out options, text messaging, and voice over a VHF / UHF radio network. To support these
options a set of commands have been added that use an ‘AV’ prefix. This chapter is used to describe
these ‘AV’ commands.

The commands are not case sensitive, upper or lower case may be used. All voice commands must
be terminated with a Carriage Return or a Carriage Return and Line Feed pair. This will not be
shown in the descriptions below.

In most cases the response to a command is the ‘OK’ message or the data or information requested
is returned. All responses will be terminated with a Carriage Return and Line Feed pair. Below the
commands are listed in upper case to help them stand out.

4.3 Data Entry Commands

Before describing the commands used to load data into the modem for voice options, it is best to
understand how the data is stored and moved around in the modem.

Currently, there is a 10 by 13 table used to hold the data values. This is basically 10 values wide for
the different types of data and 12 values deep for historical data. One extra row of data for non
scheduled updates.

Time Stamp Box 01 Box 02 Box 03 - - - Box 10

Last / Non Scheduled Update

| | | | | |

Historical Data 12

The normal sequence for a data logger to load data into the modem at a normal scheduled update
time is as follows:

AV Send the AV command just to get its attention
AVTIME=HH:MM:SS Send the time to the modem, time is stored in top box in the table.
AVBOX01=12.34 Send data for data box 01, data stored in top box of the table.
AVBOX02=56.78 Send data for data box 02, data stored in top box of the table.
AVSHIFTVALUES Shift values so data in row 12 is lost, row 11 moved to row 12, row

10 moved to row 11, continued on until row 0 is stored in row 1.

If the user requests data on demand, then the same sequence is followed except the shift command
is not issued. The new data is in row 0 and all the historical data in the other rows remains the same.

Again the data logger automatically issues these command to load the data into the modem.

Command: TIME
Description: This command is used to time tag the data sent to the modem, or to see the last time

value entered.

In a normal sequence the command AVTIME =HH:MM:SS is sent to the modem from
the logger, followed by data commands. If the command was successful then the “OK”
message will be returned.

4-4 Modem Command Reference H-219X

Example: avtime=12:15:00

OK

If the command is entered without the time portion, then the last time value entered will
be returned.

Example: avtime

Time=12:45:00

Command: BOX01 - BOX10
Description: These commands are used to send data to the modem, or to see the last value entered

for the selected data box.

In a normal sequence the command AVBOXxx =xx.xx is sent to the modem from the
logger. A separate AVBOXxx command is used for each value sent tot he modem. If
the command was successful then the “OK” message will be returned.

If the command is entered without the data value portion, then the last value entered for
the selected box will be returned.

Command: SHIFTVALUES
Description: This command is used by the data logger to shift the data in the table at scheduled

timed updates.

If the command was successful then the “OK” message will be returned.

Command: VALUES
Description: This command can be used to see all the data that is currently stored in the modem.

This includes the time stamp of when the data was received. The data will be
formatted much like the above table.

H-219X Modem Command Reference 4-5

4.4 General Voice Commands

Command: IDMESSAGE
Description: This command is used to enter the site id message that will be spoken when the unit

is called or when it calls out in a voice mode. The message can be up to 128
characters but keep in mind the longer the message, then the longer it will take to
make the call.

Example: avidmessage=This is the logan river near first dam

OK

The command can also be used to see the current message.

Example: avidmessage

ID Message = This is the logan river near first dam

Command: DATAMESSAGE01 to DATAMESSAGE10
Description: This command is used to enter the message that will be spoken to identify the data

for boxXX when the unit is called or when it calls out in a voice mode.

Command: ALARMMESSAGE0 to ALARMMESSAGE9
Description: This command is used to enter the message that will be spoken to identify an alarm

condition. This is only used when the unit calls out in a voice mode after an alarm
is detected.

Command: ALARM0 - ALARM9
Description: These commands are used to set an alarm so the unit will make outgoing calls. The

data logger will evaluate some condition to see if a call should be made. If the logger
determines an alarm condition exists, then it will set the desired alarm using this
command. The alarm is activated by setting it to a 1 and clearing the alarm by setting
it to 0.

Example: AVALARM9=1 Triggers alarm 10 and out going calls will be made.

The modem will also clear the alarm to 0 after acknowledgment. A suspended alarm will
be greater than 1.

Menu Mode Reference

5.1 Menu Mode Reverence

The easiest way to setup and test the modem is to use the built in menu mode. To enter the menu
connect a PC to the serial port and using a terminal emulation program like Hyper Term running at
9600 baud, enter the command AVMENU. The main menu should be displayed as shown below.
The example below is for the H-2192, the Cell phone option.

5.2 Remote Access

The modem menus and commands can also be accessed remotely. Normally when calling a site that
has an H-219X, the intent is to communicate with a device connected to the serial port of the H­219X. However if the device connected to the H-219X is in a sleep state, then the H-219X is
accessed by typing in commands for the H-219X. Normally the AVMENU command is used to
access the menus of the modem. As long as ‘AV’ commands are sent to the remote H-219X the
characters will not be passed on to the connected device.

If the connected is an XL series data logger and it is asleep, pressing any key other than ‘AVxxx’
will cause the characters to be sent out the serial port and wake up the XL data logger.

I - ID Message:

This option is used to enter the text that will be spoken to identify the site when the unit is called in
a voice mode. It is best to keep all the messages short so the phone call is not too long. All
messages can be up to 128 characters.

W - Welcome Message: This is the message that will be played when calling into the modem over
voice. For example if a password has been set it could be changed to “Enter Password” or left blank

H-219X Menu Mode Reference 5-3

to instruct the modem to speak nothing and waiting for a correct password before responding.

P - System Password: This option is used to set or change the password when calling the modem
in either a voice or data mode. Use a password of ‘0' to disable the password in data mode. Note:
due to the restrictions of a touch tone handset password

1 - Data Message 1:

This is the message that will be played if the data value 01 is valid. This is used to identify the data.
This is the same for all data messages, 01 to 10.

There are some special options used to enter actual data in a text message. To enter a data value that
changes from one measurement to another use the $vxx option, where the ‘$’ character indicates a
embedded code is coming. The ‘v’ character indicates the embedded code is a value, and the xx is
a number 01 to 10 for value 01 to value 10. For example if value 01 was a temperature and was

23.75, then a typical message would be: “The temperature is $v01 degrees”. Now when spoken the
unit would speak the “23.75" in place of the $v01. Other special options for the messages are listed
below.

Code Action

$Vxx The ‘V’ character stands for value. This control code is used to

insert a value into the data message. The value comes from the
data box indicated by the xx. The xx has a range of 01 to 10.
The leading zero is needed.

$Q This code is used to ‘Q’uit speaking the current message and

move on to the next message if one is needed.

$I This code inserts the current IP address assigned to the modem.

$P This code inserts the current TCP port set in the modem

Some characters cause the ‘text to voice’ converter to speak a work or perform some other function.
These are listed in the following table.

Q - Voice Quality Options:

This option is used to bring up a menu that allows the user to adjust the voice volume, speed, delays
between words, and other voice quality options. See section 5.7.1.

R - Reset Defaults:

This option resets all user programmable options back to the factory defaults.

5.9.1 Voice Quality Menu

This menu allows the user to adjust the voice quality options for their personal preference. Even
though this uses an advanced ‘Text To Speech’ converter, keep in mind there are still limitations on
range and true voice dynamics. Again, all these are changed based on user preference.

Maintenance and Trouble Shooting

6.1 Maintenance

Sustained operation of the H-2191 is almost maintenance-free. There is no desiccant or serviceable
parts to maintain. It is always best to keep the unit as dry as possible and out of direct sun light.

6.2 Trouble Shooting

It is unlikely that this manual will ever contain trouble shooting tips to cover every problem that may
be encountered. Feedback from customers is very valuable and greatly aids in the quest for constant
product enhancement. Please feel free to call the factory for technical assistance, and also to share
solutions you have found to past problems. The following paragraph present some possible solutions
to a few problems that may be encountered.

Will not answer when called:

1. The H-2191 may be busy communicating with the connected device. If so, it may not answer
the call. If connected to a WATERLOG series data logger, the H-2191 will be activated
when the data logger turns on to make a measurement, the H-2191 will be active until the
measurement is complete and data has been sent to the H-2191 data value boxes. This
normally takes 15 seconds but can be longer based on the settings and the sensors that are
connected. Wait for a minute or so and try again.

2. If the line is busy, someone else may be talking to the H-2191 or it is trying to make an out
going calls based on some alarm condition.

The “Press 1 For New Measurement” option responds with “No Data Available”:

1. The connected data logger may not be responding to commands from the H-2191 to take a
new reading. Check the cable between the H-2191 and the connected device. Make sure the
connected device is functioning properly.

2. Check the voice modem setup menu options to ensure the data to be sent to the H-2191 is
defined correctly.

3. The H-2191 may timeout before the data is ready to be sent from the data logger. Increase
the timeout associated to waiting for data. The default is 30 seconds but can be increased to
250 seconds.

H-219X Maintenance and Trouble Shooting 6-1

Voice data does not seem to be as expected:

1. The data being sent to the H-2191 is in a different order than what is expected. Check the
voice modem setup menu option to ensure the data to be sent to the H-2191 is defined
correctly and as expected.

2. The connected device is malfunctioning. The H-2191 just reports what it is given. If errors
exist in the data sent to the H-2191, the H-2191 will pass on this data including the errors as
it is not able to qualify the data. Test the device sending data to the H-2191.

Miscellaneous Problems:

1. The lack of a proper earth ground can result is several unexplained problems. Please make
sure the complete system is properly grounded.

! Double check that all the power cables are connected well.

! Low power can cause the modem to function abnormally or not at all.

! If the modem will not return to the low power mode make sure the device connected to the

serial port is turning off properly. When connected to a PC that is running a terminal
emulation program, the modem will stay on continuously.

Normally, a very high percentage of the problems can be related to power supply problems, bad or
incorrect wiring, or system options are not set up correctly. In most cases these problems can easily
be resolved. If a problem cannot be found easily call Design Analysis for technical assistance.
